Increased uptake of α-hydroxy aldehyde-modified low density lipoprotein by macrophage scavenger receptors

open access: yesJournal of Lipid Research, 2000
Reactive aldehydes can be formed during the oxidation of lipids, glucose, and amino acids and during the nonenzymatic glycation of proteins. Low density lipoprotein (LDL) modified with malondialdehyde are taken up by scavenger receptors on macrophages ...

The Role of Lipoxidation in the Pathogenesis of Diabetic Retinopathy

open access: yesFrontiers in Endocrinology, 2021
Lipids can undergo modification as a result of interaction with reactive oxygen species (ROS). For example, lipid peroxidation results in the production of a wide variety of highly reactive aldehyde species which can drive a range of disease-relevant ...
